The Town of Occoquan, in partnership with Prince William County and Fairfax Water, developed River Mill Park, a one-acre park along the Occoquan River with a public restroom, event pavilion, open space, and paved walking trail. River Mill Park was opened to the public in July of 2016 and is used by the Town to host concerts and other family-friendly events, as well as by the community for various public and private events. The public is able to request an event permit ($) for the use of the park for special events; however, it cannot be closed to the public. The park is open daily from dawn to dusk.

The site of River Mill Park was home to the former River Station Water Treatment Plant operated by Fairfax Water since 1967, after it was acquired as part of the purchase of the Alexandria Water Company. The Frederick P. Griffith, Jr. Water Treatment Plant opened in 2006, replacing River Station (decommissioned in 2007) and two other treatment plants in the Fairfax Water system. Prior to Fairfax Water’s ownership of the property, the land played a significant role in the Town’s history as it related to grist mill and iron furnace operations. The property is still owned by Fairfax Water; however, they are leasing the property to the Town for the purpose of building and maintaining River Mill Park. In 2015, demolition work removed antiquated structures that allowed a view up the river that had not been enjoyed by the public for nearly fifty years.
